Sensing Part 2: Force Sensitive Resistors and Photocells

The program I created in Processing colors a portion of a half circle based on the amount of force exerted on the FSR. The FSR voltage was read in via the Serial port, and the reading was mapped to a range between 0 degree and 180 degree. The larger the voltage reading of the FSR, the larger the portion of the half circle is colored. The program decreases the colored portion when the reading decreases.
